http://forum.thelatioclub.org/index.php?topic=10567.0I face the same problem as bro cheemeng, air-con got sound, thought is need to top up gas but was told cooling coil spoilt, as warranty over, decided not to pay more than 1k for replacement at TCM, went to toh guan autoaid and it was replaced nicely.
The mechanic there, ex-tcm staff very experience, was expecting him to remove my entire dashboard like bro cheemeng did in JB, but he say dun need, coz he know actually which clip and part to remove to access the cooling coil.
must add that i choose to use 3rd party cooling coil instead of paying extra for original. Was assured that it is as good and got 6 mths warranty, was told confidently at least 3 years no problem. My current wan also original latio cooling coil but 3.5 years also up lorry

.
replace cooling coil, evaporation valve, o ring, air-con gas foc, labour, gst etc all for around $400, comparing going into malaysia(still cheaper as using original coil) to do, i rather do it in singapore coz anything wrong still can go back easily.
nice job, now my air-con really cold & quiet
